Five races of the Eurasian silver‐studded blue butterfly, Plebejus argus, are restricted to different habitats in north Wales and north‐west England. One of these races is extinct, and others are threatened. The four extant forms differ in morphology, habitat, host plant choice, performance on different host plant species and species of associated ant. Some of these differences are maintained in captivity, suggesting evolutionary divergence. Different races with different habitat requirements… 

Divergent patterns in the mitochondrial and nuclear diversity of the specialized butterfly Plebejus argus (Lepidoptera: Lycaenidae)

The hypothesis that females are philopatric is consistent with direct observations of the restricted colonization abilities of the butterfly, while the relatively homogeneous genetic structure revealed by previous allozyme studies in some areas might be explained by the possible higher mobility of males.

Phylogenetic relationships in brown argus butterflies (Lepidoptera: Lycaenidae: Aricia) from north-western Europe

Investigation of phylogenetic relationships and phylogeographic patterns in this species group using mitochondrial and nuclear markers in comparison with morphological variation shows that the sample is composed of two closely related species, A. agestis and A. artaxerxes.

Evidence based conservation of butterflies

Within-patch larval habitat quality is again critical at the meta-population scale, explaining slightly more examples of patch occupancy than site isolation, and the higher density populations supported by optimum habitat are less likely to go extinct, and immigrants to new high-quality patches have a higher probability of founding new populations.


The results do not support the idea that patchiness promotes regional coexistence through multispecies metapopulation dynamics, and suggest that conservation recommendations must be based on detailed analysis of the requirements of each key species in order to understand their spatial dynamics.

Host compatibility as a critical factor in management unit recognition: population‐level differences in mussel–fish relationships

It is demonstrated that small-scale cross-compatibility testing can be effectively used to diagnose the sources of variability in host relationships with direct management implications, and can enhance the targeting of management actions in many biological applications addressing species conservation, biological invasions and ecosystem processes.

Considering Local Adaptation in Issues of Lepidopteran Conservation—a Review and Recommendations

The importance of considering local adaptation in butterfly conservation is addressed and investigations of regional specialization that may enhance the effectiveness of conservation strategies such as captive rearing, habitat restoration and the introduction of populations into new localities are encouraged.

A new method to identify important conservation areas applied to the butterflies of the Aegean Islands (Greece)

The new method is applied here to the butterflies of the Aegean Islands (Greece) using different (national and international) red lists and results were consistent with both classifications based on multivariate analyses and findings from other researches.


One major goal of conservation biology in fragmented landscapes is to identify the attributes of habitat networks that influence metapopulation persistence, and thereby to determine whether

Deeply transformed environments due to human impact have high bird densities and species richness, even higher than those measured in native, unmodified habitats such as laurel forests or mature pinewoods.

For the first time, a list of the current accepted plant names utilised by 471 European butterfly larvae is presented, with references, and errors in previous lists have been removed.



Intraspecific variation in habitat availability among ectothermic animals near their climatic limits and their centres of range

The model predicts that an increase of 2–3 °C can result in a large increase in the area of habitat available to these north temperate species, that the length of time that individual patches of successional habitat may be occupied increases and that the distance between habitat patches within the biotope decreases.

Three ways of assessing metapopulation structure in the butterfly Plebejus argus

1. Three independent methods were used to investigate population structure in the butterflyPlebejus argus . First, migration and dispersal ability were measured by mark–release–recapture in seven

Spatial dynamics of a patchily distributed butterfly species

The regional distribution was constrained by the inability of the butterfly to colonize suitable habitat that was further than a fex kilometres from existing metapopulation; some of these sites are now populated by P.argus following successful introductions.

Evolutionary consequences of habitat fragmentation in a localized butterfly

Significant family effects for total mass, relative thoraxmass, relative abdomen mass and (for females only) relative wing area indicate that these traits may have a heritable component, and therefore have the potential to respond to selection acting on flight ability.

Molecular population structure and the biogeographic history of a regional fauna : a case history with lessons for conservation biology

These concordant phylogeographic patterns among independently evolving species provide evidence of similar vicariant histories of population separation, and can be related tentatively to episodic changes in environmental conditions during the Pleistocene.

Population diversity: its extent and extinction.

This work estimates the number of populations per area of a sample of species from literature on population differentiation and the average range area of an species from a samples of distribution maps, which yields an estimate of about 220 populations per species.

Abstract. 1. The polyphagous butterfly, Plebejus argus L., was found to have specialized requirements: eggs are laid along vegetation/bare ground margins, larvae specialize on tender meristematic and
